CAR-TRUCK CONSTRUCTION.

SPECIFICATION forming part of Letters Patent N 0. 709,072, dated September 16, 190.2. Application filed February 25,1902. Serial No. 95,560- (No model.)

To all whom it may concern:

Be it known that I, WALTER S. ADAMS, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, (whose post-office address is care of the J. G. Brill Company, Sixty-second street and Woodland avenue, in said city,) have invented certain new and useful Improvements in Oar-Truck Constructions, of

[O which the following is a specification.

My invention has for its object to provide a simple and efiicient connection for crossbars, spring or sand planks of a truck with the side bars or side frames or the :5 equalizingbars of trucks.

My invention therefore resides in the novel construction of what I term a cross-bar carrier and its combination with other elements, as well as the other details of improvement hereinafter described, and further pointed out in the claims. V

In the drawings forming part of this specification, Figure l is a plan view showing the application of myinvention to an equalizingbar. Fig. 2 is a front elevation of Fig. 1.

Fig. 3 is a sectional elevation on the line A B,

Fig. 2; Fig. 4, a sectional elevation on the line C D, Fig. 1. Fig. 5 is a front elevation of the equalizing-bar. Fig. 6 is a view of the cross-bar carrier; Figs. 7 and 7, a plan of a portion of one end of the cross-bar and a sectional elevation of the cross-bar, respectively; Fig. 8, a face view of the end of the cross-bar; Fig. 9, a sectional elevation through the equal- 5 izing-bar; Fig. 10, a like View through the crossbar carrier; Fig. 11, a plan view showin g the application of my invention to a truck side frame, a portion of the side frame and cross-bar being shown. Fig. 12 is a front view of Fig. 11; Fig. 13, a cross-section of the truck side bar; Fig. 14., a sectional elevation on the line E F, Fig. 12; Fig. 15, a section of the cross-bar carrier;-Fig. 16, a front elevation of the cross-bar carrier; Figs. 17 to 21, inelusive, a section of the cross-bar, a plan of one end of the latter, a front elevation of the latter, and a plan and side elevation of a portion of the side bar.

I shall first describe my invention as it is employed in connection with the spring-plank and equalizing-bar of the type of truck illustrated in Letters Patent granted to G. M. Brill and S. W. Ourwen, Nos. 610,118 and 610,119, dated August 30, 1898, to which patents cross-reference is made, in which truck the equalizing-bar is supported on the side frames of the truck by swinging spring-links and in which the spring or sand planks connect the equalizing-bars at each side of the truck together. 1

Referring to present Figs. 1 to 10, inclusive, 1 indicates the sand or spring plank, generically comprising the wooden plank 2, the cross-bars 3, bolted to the plank, and 4c the equalizing-bar. The cross-bars comprise flat bars disposed on edge having their ends 5 turned at an angle therefrom and provided with holes 6. The equalizing-bar 4 is, as shown, rectangular in cross-section. At 7, Fig. 10, is the cross-bar carrier, which comprises, preferably, a piece of metal (cast or otherwise produced) having a vertical web 8 and longitudinal flanges 9 10, extending outwardly from the upper and lower edges of the web at each side or, in other words, in opposite directions from each other. Both the web 8 and the cross-bar carrier, the equalizing-bar 4, and the bent ends 5 of the crossbars 3 are provided with holes 6 11 12. In assembling the parts together the cross-bar 8o carrier is laid against the vertical face of the equalizing-bar, (in the present embodiment the inside face,) so that the upper flange 9 overlaps the top of the equalizing-bar with the lower flange 10 presented inwardly, and upon this lower flange and against the inner face of the vertical web 8 of the carrier the bent ends 5 of the cross-bars 3 are placed. Bolts 13 are then passed through the ends of the cross-bars, the cross-bar carrier, and equalizing-bar, whereby these parts are securely held together, the lower flange 1O supporting the cross-bar and the parts attached thereto, the upper flange supporting the carrier and the parts attached to it on the equal- 5 izing-bar, the bolts securing these parts firmly together and tying the two equalizing-bars at each side of the truck firmly together. This construction provides an expeditious and economical means for uniting ihese parts to- I00 gether for dismembering or dismantling them for repair, &c., and the support of the spring plank and bolster and cross-bars is had upon the lower flange of the carrier, thereby taking all the strain, the bolts merely being employed to secure the parts together, and likewise the strain of supporting the cross-bars is taken on the upper flange and ultimately on the equalizing-bar, thereby relieving the bolts of this strain also. As a specific improvement in this direction the sand or spring plank 2, preferably of wood, (although it may be constructed of different material,) has its ends 14 resting upon the lower flange 10 of the carrier and is secured to the cross-bars by the transverse bolts 15, passing through the cross-bars and the plank. This construction also, while enabling the parts to be expeditiously assembled or disassembled, relieves the bolts 13 of the strain of supporting the plank.

It is clear, so far as the specific device for securing a cross-bar, such as 3, and an equalizing-bar, such as 4, together is concerned, that it, the cross-bar carrier, and a cross-bar having a bent end or web or enlargement presented at an angle to its main dimension, can be employed in other relations and still embody my invention.

Another specific manner of utilizing my invention is as illustrated in Figs. 11 to 21, in which 16 is a section of the side bar of the truck, (such as is illustrated in the patent to J. A. Brill and myself, dated May 7, 1895, No. 538,948, to which cross-reference is here made,) and 3 the cross-bar, the side bar having holes 17 formed therein for attachment of the carrier. The carrier is constructed as heretofore described, and the other parts may be likewise,as previously described. As illustrated, the only difference is in the dimension, this being made necessary from the fact that but one cross-bar is used instead of a plurality. The parts are assembled as before described, and one of the bolts 18 19, connecting the cross-bar and the side bar, may have a chain carrier 20 at its outer end, as is usual.

Having described my invention, 1 claim- 1. The combination with the cross-bar having a bent end, another bar, and an interposed carrier having flanges extending from its upper and lower edge in opposite directions and vertically disalined, the bent end resting on the flange, the upper flange resting upon the latter bar, and means for detachably securing the bars together, substantially as described.

2. The combination with the spring-plank, cross-bars upon each side thereof having laterally-projecting ends substantially at right angles to said spring-plank, and a cross-bar supporter; of a cross-bar carrier interposed between said cross-bars and cross-bar supporter having a vertical web and longitudinally-disposed separated flanges extending therefrom in opposite directions, one of said flanges resting upon the upper side of said cross-bar supporter, and the lower flange resting beneath and supporting the end of said spring-plank and the outwardly-turned ends of said cross bars upon each side of said spring-plank.

3. The combination with the spring-plank, and a cross-bar carried upon each side of said spring-plank havinglaterally-extending ends, and a cross-bar su pporter carried by the truckframe; of a cross-bar carrier interposed be tween the end of said plank and said support, oppositely-disposed flanges carried by said carrier, the flange upon the top of said carrier resting upon the upper side of said support, and the lower flange resting beneath and supporting the under side of said springplank and the laterally-extending ends of said cross-bars, and bolts passing through said cross-bar, cross-bar carrier and support for detachably securing said parts together.

. 4E. The combination with the spring-plank, cross-bars having laterally-projecting ends bolted to each side of said spring-plank, and cross-bar supports carried by the truck-frame; of a flanged carrier interposed between the end of said spring-plank, and the laterallyprojecting ends of said cross-bars and said support, and means for detachably securing said parts together.

5. The combination with the spring-plank, cross-bars secured to each side of said springplank having their ends projecting laterally from said plank in a plane substantially in line with the end of said spring-plank, and means carried by the truck for supporting said cross-bars and spring-plank; of a crossbar carrier having a vertical web interposed between the end of said spring-plank and cross-bars and said support, and oppositelydisposed flanges carried by said web, the upper flange resting upon the upper side of said support, and the lower flange resting beneath and supporting the end of said spring-plank and the laterally projecting ends of said cross-bars, and bolts passing through said laterally-projecting portions of said cross-bars and through said cross-bar carrier and support for detachably securing said parts together.
